Description

Technical Field

[0001] This utility model relates to the technical field of vehicle rear wing mounting structure, specifically to an electric rear wing mounting structure and a vehicle. Background Technology

[0002] Equipping a car's hatchback with an electric rear spoiler not only improves aerodynamics, reduces wind resistance, and enhances driving stability and safety, but also creates a unique visual effect. However, to install the electric rear spoiler, a large hole is cut into the hatchback's outer panel, significantly reducing its rigidity. Furthermore, to accommodate the electric spoiler's drive mechanism, a large cavity is created between the outer and inner panels, resulting in insufficient hatchback support. This is especially problematic in mid-to-high-end B-segment and C-segment vehicles, where hatchbacks often feature enlarged rear windows for a wider field of vision, further weakening the hatchback's rigidity. This reduced rigidity also makes hatchbacks with electric spoilers prone to resonance, leading to vibration and noise issues. Utility Model Content

[0003] One objective of this utility model is to provide an electric rear wing mounting structure to solve the technical problem in the prior art where the stiffness of the hatchback itself and the support stiffness decrease, resulting in vibration and noise; the second objective is to provide a vehicle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows.

[0005] The electric tail wing mounting structure includes:

[0006] A hatchback assembly includes a hatchback inner panel, a hatchback outer panel, and a reinforcing member. The reinforcing member is welded to the hatchback inner panel, and an installation window is provided on the hatchback outer panel.

[0007] The drive assembly includes a mounting component and a drive mechanism fixed to the mounting component. The mounting component is fastened to the mounting window. The mounting component, the hatchback outer panel, and the reinforcing member are stacked in sequence and then fastened together by bolts.

[0008] An electric rear spoiler is disposed on the side of the outer panel of the hatchback door away from the inner panel of the hatchback door, and the electric rear spoiler is connected to the drive assembly.

[0009] By employing the aforementioned technical methods, a reinforcing member is installed between the outer and inner panels of the hatchback door. This member, secured with bolts to the mounting components and the outer panel, forms a layered, tightly fastened structure. This effectively enhances the rigidity of the hatchback in the area where the electric rear spoiler is installed, preventing resonance issues caused by structural weakening. It also reduces noise and vibration during vehicle operation, improving overall vehicle performance and ride comfort. Specifically, the reinforcing member between the inner and outer panels strengthens the outer panel's rigidity while simultaneously increasing its supporting rigidity, thereby reducing vibration and resonance in the hatchback assembly during driving, thus lowering interior noise and improving ride comfort. Furthermore, the sequential layering and bolting of the mounting components, outer panel, and reinforcing member into a single, integrated structure allows all three components to share bolt mounting points, facilitating manufacturing and installation, improving assembly efficiency, and reducing production costs.

[0010] Furthermore, in the electric tail wing mounting structure, the reinforcing member includes a first welding flange, a second welding flange, and a third welding flange. The line connecting the first welding flange, the second welding flange, and the third welding flange forms a triangular structure. The inner panel of the hatchback door is provided with a first welding boss that cooperates with the first welding flange, a second welding boss that cooperates with the second welding flange, and a third welding boss that cooperates with the third welding flange.

[0011] Through the above technical means, the first welded flange, the second welded flange, and the third welded flange together form a "triangular" bottom support structure, which can effectively disperse the load concentration problem caused by the installation of the tail wing in a local area, improve the fatigue life and deformation resistance of the overall structure of the hatchback, and ensure that the electric tail wing can still maintain stable operation under frequent lifting or high-speed wind pressure impact.

[0012] Furthermore, in the electric tail wing mounting structure, the reinforcing member also includes a main board. The edge of the main board includes a first edge, a second edge, a third edge, a fourth edge, and a fifth edge that are connected end to end in sequence. The second edge and the fifth edge are directly opposite each other. The third edge and the fourth edge are generally directly opposite the first edge. A raised reinforcing rib is formed on the main board. The reinforcing rib extends from the connection between the third edge and the fourth edge to the middle of the first edge.

[0013] Through the above technical means, the first edge, the second edge, the third edge, the fourth edge, and the fifth edge that are connected end to end, together with the reinforcing rib, are roughly in the configuration of a Chinese character 'Ri' in the plan view, making the main board form a closed frame structure, which has stronger structural integrity and anti-deformation ability, and can withstand torques and loads from different directions during the driving of the tail wing. Especially in the case of high-speed driving and frequent actions of the electric tail wing, it is more helpful to prevent local structural fatigue or deformation. Being arranged between the inner panel and the outer panel of the hatchback door can, to a certain extent, alleviate the problem of local deformation or insufficient stiffness caused by the opening of the outer panel of the hatchback door in the overall hatchback door.

[0014] Further, in the electric tail wing installation structure, the reinforcing member further includes a first bending plate, a second bending plate, and a third bending plate for connecting with the outer panel of the hatchback door. The first bending plate is connected to the third edge, the second bending plate is connected to the fourth edge, the third bending plate is connected to the fifth edge, the third edge and the fourth edge are arranged at an angle, and the connection points of the first bending plate, the second bending plate, and the main board are located outside the plane of the triangle formed by the first welding flange, the second welding flange, and the third welding flange.

[0015] Through the above technical means, a conical configuration with highly three-dimensional structural characteristics is formed, which can enhance the three-dimensional support ability. The conical structure forms multi-angle support paths in space, improving the vibration resistance and torsional resistance of the entire reinforcing member, effectively reducing the vibration and resonance of the hatchback door caused by the movement of the tail wing during vehicle driving; enabling the load to be effectively transmitted and dispersed along multiple paths, reducing the risk of local structural fatigue.

[0016] Further, in the electric tail wing installation structure, the first welding flange is connected to the connection part of the second edge and the first bending plate, the second welding flange is arranged at the connection part of the reinforcing rib and the first edge, and the third welding flange is connected to the connection part of the third bending plate and the first edge.

[0017] Through the above technical means, the reinforcing member forms a 'three-dimensional triangular pyramid' closed-loop support structure in space, which has good compressive and shear resistance, can significantly improve the stability of the structure under the working conditions of vehicle acceleration, braking, and bump impact, effectively inhibit the occurrence of fatigue cracks, and extend the service life of the system. And the spatial structure of the triangular pyramid support structure is compact, occupying a small space. Compared with the traditional planar reinforcement plate, this triangular pyramid reinforcing member realizes a good force layout with a small volume.

[0018] Furthermore, in the electric tail wing mounting structure, a recessed first positioning part is formed on the first bending plate, and a first fixing hole is formed on the first positioning part and on the first bending plate on both sides of the first positioning part; a fourth bending plate is formed on the outer panel of the hatchback door to cooperate with the first bending plate, a second positioning part is formed on the fourth bending plate to cooperate with the first positioning part, and a second fixing hole is formed on the second positioning part and the fourth bending plate on both sides of the second positioning part to cooperate with the first fixing hole.

[0019] Through the above technical means, the first and fourth bending plates achieve the dual functions of positioning and limiting as well as multi-point fixing, effectively improving assembly accuracy and structural strength.

[0020] Furthermore, in the electric tail wing mounting structure, a wiring harness assembly clearance hole and a welding process clearance hole are provided on the main board between the second edge and the reinforcing rib, and a stamping process clearance hole is provided on the main board between the fifth edge and the reinforcing rib.

[0021] Through the above technical means, the wiring harness assembly clearance holes provide a space channel when the electric rear spoiler system wiring harness assembly passes through the reinforcement, allowing the wiring harness to smoothly bypass the reinforcement area during installation, avoiding damage, squeezing, or excessive bending. It also facilitates the placement of wiring harness fixing clamps, improving the reliability of the vehicle's electrical system. The welding process clearance holes provide operating space for the welding gun or welding head during the welding process, especially suitable for avoiding the reinforcement when spot welding or resistance welding with the inner and outer panels of the hatchback door, making the welding operation more convenient, improving welding quality, and preventing problems such as mis-welding or incomplete welding. The stamping process clearance holes are designed to alleviate stress concentration problems caused by complex curved surface transitions and angle changes during sheet metal forming.

[0022] Furthermore, in the electric tail wing mounting structure, the mounting component includes a decorative panel and bowl-shaped components located at both ends of the decorative panel. The opening direction of the bowl-shaped components is away from the inner panel of the hatchback door. The driving mechanism includes a drive motor, a transmission component, and a drive hinge. The drive motor is fixed on the decorative panel, and the drive hinge is disposed inside the bowl-shaped components. The drive motor drives the drive hinge to move through the transmission component, and the electric tail wing is mounted on the drive hinge.

[0023] Using the above technical means, the decorative panel and bowl-shaped component are used to cover the surrounding area of ​​the mounting window on the outer panel of the hatchback door, serving the dual purpose of aesthetic coverage and structural support. The bowl-shaped component has an outward-facing opening, meaning its opening direction is away from the inner panel of the hatchback door. This configuration allows the decorative panel to cover and conceal most of the drive mechanism, while providing the necessary space for coordination with the external electric tail wing while ensuring a compact appearance.

[0024] Furthermore, in the electric tail wing mounting structure, two reinforcing members are provided, respectively located on both sides of the extension direction of the mounting window.

[0025] Through the above technical means, the two reinforcing members can provide symmetrically distributed structural support points on both sides of the electric tail wing mounting area, which not only facilitates the distributed installation of the drive mechanism, but also significantly improves the overall torsional stiffness and impact stability of the entire electric tail wing mounting structure.

[0026] A vehicle comprising an electrically powered rear wing mounting structure.

[0027] The beneficial effects of this utility model are:

[0028] (1) In the installation structure provided in the embodiments of this application, a reinforcing member is provided between the outer panel and the inner panel of the hatchback door, and a stacked fastening structure is formed between the reinforcing member and the mounting member and the outer panel of the hatchback door by bolts. This can effectively improve the rigid support capacity of the hatchback door in the electric rear spoiler installation area, avoid resonance problems caused by structural weakening, reduce noise and vibration during vehicle operation, and improve the overall vehicle performance and ride comfort. That is, the reinforcing member provided between the inner panel and the outer panel of the hatchback door can improve the support rigidity of the outer panel of the hatchback door while reinforcing the rigidity of the outer panel itself, thereby reducing the vibration and resonance of the hatchback door assembly during vehicle operation, thereby reducing in-vehicle noise and improving ride comfort.

[0029] (2) In the installation structure provided in this application embodiment, the mounting component, the outer panel of the hatchback door and the reinforcing component are stacked in sequence and then fastened together by bolts, so that the mounting component, the outer panel of the hatchback door and the reinforcing component are fixed as an integral structure, and the three structural components can share the bolt installation points, which facilitates manufacturing and installation, improves assembly efficiency and reduces production costs.

[0048] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0049] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0050] like Figure 1-11 As shown, this embodiment proposes an electric tail wing mounting structure, which mainly includes a hatchback assembly 3, a drive assembly 2, and an electric tail wing 1. The hatchback assembly 3 includes an inner hatchback panel 31, an outer hatchback panel 32, and a reinforcing member 34. The reinforcing member 34 is welded to the inner hatchback panel 31, and the outer hatchback panel 32 has a mounting window 321. The drive assembly 2 includes a mounting member 22 and a drive mechanism fixed to the mounting member 22. The mounting member 22 is fastened to the mounting window 321. The mounting member 22, the outer hatchback panel 32, and the reinforcing member 34 are stacked sequentially and then fastened together with bolts. The electric tail wing 1 is located on the side of the outer hatchback panel 32 facing away from the inner hatchback panel 31, and the electric tail wing 1 is connected to the drive assembly 2.

[0051] The hatchback assembly 3 is installed at the rear of the vehicle for opening and closing the vehicle's trunk. The hatchback assembly 3 includes an inner hatchback panel 31 and an outer hatchback panel 32. The inner hatchback panel 31 faces inwards towards the vehicle's interior, while the outer hatchback panel 32 is located outside the inner hatchback panel 31 and faces outwards towards the vehicle's exterior. In this document, "inner side" and "outer side" are relative to the vehicle's spatial coordinates; "inner side" refers to the side facing the vehicle's interior space, and "outer side" refers to the side facing the vehicle's exterior space.

[0052] The mounting window 321 on the outer hatch panel 32 is used to accommodate the installation drive mechanism, which provides power for the deployment and retraction of the electric rear wing 1. In practical use, the structural rigidity of the outer hatch panel 32 may be weakened to some extent due to the mounting window 321. However, by setting a reinforcing member 34 between the outer hatch panel 32 and the inner hatch panel 31, and using bolts to form a stacked and fastened structure with the mounting member 22 and the outer hatch panel 32, the rigid support capacity of the hatch in the installation area of ​​the electric rear wing 1 can be effectively improved, avoiding resonance problems caused by structural weakening, reducing noise and vibration during vehicle operation, and improving overall vehicle performance and ride comfort. That is, the reinforcing member 34 set between the inner hatch panel 31 and the outer hatch panel 32 not only strengthens the rigidity of the outer hatch panel 32 itself, but also increases the support rigidity of the outer hatch panel 32, thereby reducing the vibration and resonance of the hatch assembly 3 during vehicle operation, thus reducing in-vehicle noise and improving ride comfort. On the other hand, the mounting component 22, the hatchback outer panel 32, and the reinforcing component 34 are stacked in sequence and then fastened together with bolts, which can fix the mounting component 22, the hatchback outer panel 32, and the reinforcing component 34 into an integral structure. Furthermore, the three structural components can share the bolt mounting point 111, which facilitates manufacturing and installation, improves assembly efficiency, and reduces production costs.

[0053] In some implementations, in the electric tail wing mounting structure, such as Figure 6 and 10 As shown, the reinforcing member 34 includes a first welding flange 341, a second welding flange 344, and a third welding flange 3410. The line connecting the first welding flange 341, the second welding flange 344, and the third welding flange 3410 forms a triangular structure. The inner panel 31 of the hatchback door is provided with a first welding boss 301 that cooperates with the first welding flange 341, a second welding boss 303 that cooperates with the second welding flange 344, and a third welding boss 304 that cooperates with the third welding flange 3410.

[0054] like Figure 7As shown, the lines connecting the first welding flange 341, the second welding flange 344, and the third welding flange 3410 form a triangular structure. This structure can form a stable spatial support frame, significantly improving the torsional rigidity of the reinforcing member 34 and the support stability of the local area of ​​the hatchback door. The three points form a surface, which is more resistant to the multi-directional forces and dynamic impacts generated when the electric tail wing 1 is driven compared to a single reinforcing rib 348 structure. To facilitate the precise positioning and efficient welding of the above-mentioned flange structure, the inner panel 31 of the hatchback door is correspondingly provided with a first welding boss 301, a second welding boss 303, and a third welding boss 304, which are used to weld with the first welding flange 341, the second welding flange 344, and the third welding flange 3410, respectively. The cooperation of the above three sets of welding bosses with the welding flanges not only helps to improve the accuracy of welding positioning, but also enhances the stability and durability of the weld, thereby improving the overall bonding strength between the inner panel 31 of the hatchback door and the reinforcing member 34.

[0055] Through this structural design, the first welded flange 341, the second welded flange 344, and the third welded flange 3410 together form a "triangular" bottom support structure, which can effectively disperse the load concentration problem caused by the installation of the tail wing in a local area, improve the fatigue life and deformation resistance of the overall structure of the hatchback, and ensure that the electric tail wing 1 can still maintain stable operation under frequent lifting or high-speed wind pressure impact.

[0056] In some embodiments, to further enhance the structural support capacity of the mounting area of ​​the electric rear wing 1 and the overall rigidity of the hatchback assembly 3, the electric rear wing mounting structure may include, for example... Figure 6 As shown, the reinforcing member 34 also includes a main board 340, which is disposed between the outer panel 32 and the inner panel 31 of the hatchback door and serves as the main load-bearing component of the reinforcing member 34. The edges of the main board 340 include a first edge 3401, a second edge 3402, a third edge 3403, a fourth edge 3404, and a fifth edge 3405 connected end to end. The second edge 3402 and the fifth edge 3405 are directly opposite each other. The third edge 3403 and the fourth edge 3404 are generally directly opposite the first edge 3401. A raised reinforcing rib 348 is formed on the main board 340, which extends from the connection between the third edge 3403 and the fourth edge 3404 to the middle of the first edge 3401.

[0057] like Figure 8As shown, the first edge 3401, the second edge 3402, the third edge 3403, the fourth edge 3404, and the fifth edge 3405 that are connected end to end, together with the reinforcing rib 348, have a configuration in a plan view that is roughly in the shape of a Chinese character 'Ri' (日), such that the main board 340 forms a closed frame structure. Specifically, the first edge 3401 forms the vertical border on the left side of the 'Ri' shape; the second edge 3402 and the fifth edge 3405 respectively form the horizontal borders at the top and bottom of the 'Ri' shape, and are arranged opposite to each other; the third edge 3403 and the fourth edge 3404 as a whole form the vertical border on the right side of the 'Ri' shape, and are arranged opposite to the first edge 3401. In this way, the five edges enclose a frame configuration approximately in the shape of a 'Ri', making the main board 340 present a strengthened frame with a structural closed loop. To further improve the in-plane stiffness of the main board 340, a reinforcing rib 348 extending along the middle horizontal direction of the 'Ri' shape is also formed on the main board 340. This reinforcing rib 348 starts from the connection area between the third edge 3403 and the fourth edge 3404, extends towards the direction of the first edge 3401, and finally extends to the middle area of the first edge 3401. The reinforcing rib 348 is arranged in the middle part of the 'Ri' shape and exactly forms the middle horizontal of the 'Ri' structure.

[0058] On the one hand, the edge arrangement in the shape of a 'Ri' forms a closed frame with high stability. This kind of 'Ri'-shaped closed-loop border structure has stronger structural integrity and anti-deformation ability compared with the open structure. It can withstand torques and loads from different directions during the driving process of the tail wing, especially in the case of high-speed driving and frequent actions of the electric tail wing 1. It is more helpful to prevent local structural fatigue or deformation. Being arranged between the inner panel 31 and the outer panel 32 of the hatchback door can, to a certain extent, alleviate the problem of local deformation or insufficient stiffness caused by the opening of the outer panel 32 of the hatchback door in the hatchback door assembly 3; on the other hand, the middle reinforcing rib 348 forms a secondary support inside the 'Ri'-shaped frame, which helps to form a support path in the middle area of the main board 340, making the overall stress of the main board 340 more uniform when it is subjected to external force impacts. It can effectively improve the bending and torsion resistance performance of the board surface and avoid deformation or cracks caused by local stress concentration.

[0059] In some embodiments, in the electric tail wing installation structure, such as Figure 6As shown, the reinforcing member 34 also includes a first bending plate 3414, a second bending plate 3415, and a third bending plate 3416 for connection with the outer panel 32 of the hatchback door. The first bending plate 3414 is connected to the third edge 3403, the second bending plate 3415 is connected to the fourth edge 3404, and the third bending plate 3416 is connected to the fifth edge 3405. The third edge 3403 and the fourth edge 3404 are set at an angle. The connection point of the first bending plate 3414, the second bending plate 3415, and the main plate 340 is located outside the plane of the triangle formed by the first welded flange 341, the second welded flange 344, and the third welded flange 3410.

[0060] The third edge 3403 and the fourth edge 3404 are set at an angle, thus creating an angle between the first bent plate 3414 and the second bent plate 3415. The first bent plate 3414, the second bent plate 3415, and the third bent plate 3416 are not on the same plane, but are arranged spatially around the edge of the main plate 340. To achieve structural stability in three-dimensional space, the connection points between the first bent plate 3414, the second bent plate 3415, and the main plate 340 are arranged outside the plane of the triangle formed by the first welded flange 341, the second welded flange 344, and the third welded flange 3410. That is, the installation area of ​​these bent plates extends to the periphery of this triangular plane, forming a conical configuration with highly three-dimensional structural characteristics. This structure forms a rigid support unit similar to a pyramid shape, with the entire reinforcing member 34 exhibiting a spatially expanded, cone-shaped upright form. This structure has the following technical advantages:

[0061] First, it can enhance the three-dimensional support capability: by bending and extending the first bending plate 3414, the second bending plate 3415 and the third bending plate 3416 outward relative to the main board 340, and arranging them at a three-dimensional angle with the main board 340, the overall structure forms a spatial rigid body with depth, which effectively enhances the three-dimensional support performance of the load-bearing area of ​​the hatchback outer panel 32.

[0062] Secondly, it helps to suppress vibration and resonance: the conical structure forms a multi-angle support path in space, which improves the vibration resistance and torsional resistance of the entire reinforcement 34, effectively reducing the vibration and resonance of the hatchback door caused by the movement of the rear wing during vehicle operation.

[0063] Third, effectively disperse the load at the installation point of the electric tail wing 1: the torque generated by the electric tail wing 1 during operation can form a complete force closed loop through the mounting part 22-hatchback door outer panel 32-bending plate-main board 340-welded flange-hatchback door inner panel 31, so that the load can be effectively transmitted and dispersed along multiple paths, reducing the risk of local structural fatigue.

[0064] In summary, the reinforcing member 34, through the construction of the first bending plate 3414, the second bending plate 3415 and the third bending plate 3416, in conjunction with the edge of the main board 340 and the triangular welding flange area, not only achieves three-dimensionality and rigidity enhancement in the spatial structure, but also effectively solves the problem of rigidity degradation caused by the opening of the window on the outer panel 32 of the hatchback door.

[0065] In some implementations, in the electric tail wing mounting structure, such as Figure 6 and 7 As shown, the first welded flange 341 is connected to the connection between the second edge 3402 and the first bent plate 3414, the second welded flange 344 is located at the connection between the reinforcing rib 348 and the first edge 3401, and the third welded flange 3410 is connected to the connection between the third bent plate 3416 and the first edge 3401. Thus, the three structures—the first welded flange 341, the second welded flange 344, and the third welded flange 3410—connecting to the inner panel 31 of the hatchback door serve as three endpoints, and the connection point between the first bent plate 3414, the second bent plate 3415, and the main plate 340 serves as the fourth endpoint, causing the reinforcing member 34 to form a closed-loop support structure resembling a three-dimensional triangular pyramid in space.

[0066] Three welding flanges are respectively set at the three key boundary nodes of the reinforcing member 34, and correspond to the first welding boss 301, the second welding boss 303, and the third welding boss 304 of the inner panel 31 of the hatchback door, to achieve a high-strength welded connection between the reinforcing member 34 and the inner panel 31 of the hatchback door, thus forming three fixed support points for the reinforcing member 34. The connection points of the first bending plate 3414 and the second bending plate 3415 with the main plate 340 and their surrounding areas are connected to the outer panel 32 of the hatchback door through a bending structure, serving as the main stress points of the reinforcing member 34 on the outer panel side. The triangular pyramid support structure formed by the four points makes the installation of the reinforcing member 34 in the hatchback door assembly 3 three-dimensional, effectively preventing problems such as structural warping and local deformation. The load borne by the tail wing mounting point 111 is transferred to multiple welding points of the inner panel 31 of the hatchback door through the triangular pyramid structure in a multi-path manner in space, reducing the stress at a single point and improving the overall rigidity of the hatchback door assembly 3. The triangular pyramid structure possesses excellent compressive and shear strength, significantly improving structural stability under vehicle acceleration, braking, and bumpy impact conditions. It effectively suppresses fatigue cracks and extends system lifespan. Furthermore, the triangular pyramid support structure is compact and occupies little space. Compared to traditional planar reinforcing plates, this triangular pyramid reinforcement 34 achieves a good stress distribution with a small volume, making it suitable for the limited installation space at the rear of vehicles and exhibiting excellent engineering adaptability.

[0067] In some implementations, in the electric tail wing mounting structure, such as Figure 6 and 10As shown, a recessed first positioning portion 347 is formed on the first bending plate 3414, and first fixing holes 346 are formed on the first positioning portion 347 and on the first bending plates 3414 on both sides of the first positioning portion 347. A fourth bending plate 323 is formed on the outer panel 32 of the hatchback door that cooperates with the first bending plate 3414. A second positioning portion 326 is formed on the fourth bending plate 323 that cooperates with the first positioning portion 347. Second fixing holes 327 that cooperate with the first fixing holes 346 are formed on the second positioning portion 326 and on the fourth bending plates 323 on both sides of the second positioning portion 326. The first positioning portion 347 can be used to achieve the initial positioning alignment of the reinforcing member 34 during the installation process. The first fixing holes 346 are formed on the first bending plates 3414 on the body of the first positioning portion 347 and on both sides of it for subsequent fixing installation of screws or rivets. Correspondingly, the fourth bending plate 323 is integrally formed into the structure of the hatchback outer panel 32 through a metal plate bending process. The second positioning part 326 correspondingly provided on the fourth bending plate 323 is complementary in shape to the first positioning part 347, forming a limiting fit structure. In addition, the second positioning part 326 and the fourth bending plate 323 on both sides are respectively provided with second fixing holes 327, which correspond one-to-one with the first fixing holes 346, for screwing or riveting, so that the reinforcing member 34 is firmly connected to the hatchback outer panel 32 and the mounting member 22. Through the above-mentioned fit relationship, the first bending plate 3414 and the fourth bending plate 323 achieve the dual functions of positioning and limiting and multi-point fixing, effectively improving the assembly accuracy and structural strength. Preferably, an integrally formed bolt 221 can be provided on the inner side of the mounting member 22, so that the integrally formed bolt 221 directly passes through the second fixing hole 327 and the first fixing hole 346 in sequence during installation, improving assembly efficiency.

[0068] In addition, such as Figure 10 As shown, a fifth bent plate 324 that cooperates with the second bent plate 3415 and a sixth bent plate 325 that cooperates with the third bent plate 3416 are formed on the outer panel 32 of the hatchback door. The fourth bent plate 323, the fifth bent plate 324 and the sixth bent plate 325 are extended sequentially on the outer panel 32 of the hatchback door, and together they enclose a semi-closed space structure, which constitutes a "semi-enclosed" structural layout. This is used to cover and limit the three bent edges of the reinforcing member 34, so that the multiple bent plates of the reinforcing member 34 are effectively limited in different directions. This achieves multi-point support, limiting guidance and reliable fixation of the reinforcing member 34, and avoids component displacement or loosening during vehicle driving and the operation of the electric rear wing 1. This further ensures the structural stability and safety of the electric rear wing 1 during the driving process.

[0069] In some implementations, in the electric tail wing mounting structure, such as Figure 6As shown, a wire harness assembly clearance hole 342 and a welding process clearance hole 343 are provided on the main board 340 between the second edge 3402 and the reinforcing rib 348, and a stamping process clearance hole 345 is provided on the main board 340 between the fifth edge 3405 and the reinforcing rib 348.

[0070] The wiring harness assembly clearance hole 342 provides a space channel when the wiring harness assembly of the electric rear spoiler 1 system passes through the reinforcement 34, allowing the wiring harness to smoothly bypass the reinforcement 34 area during installation, avoiding damage, squeezing, or excessive bending. It also facilitates the placement of wiring harness fixing clamps, improving the reliability of the vehicle's electrical system. The welding process clearance hole 343 provides operating space for the welding gun or welding head during welding, especially suitable for avoiding the reinforcement 34 when spot welding or resistance welding is performed between it and the inner or outer panel of the hatchback door, making welding operations more convenient, improving welding quality, and preventing problems such as mis-welding or incomplete welding. The stamping process clearance hole 345 is designed to alleviate stress concentration problems caused by complex curved surface transitions and angle changes during sheet metal forming. To further improve forming quality, a boss feature or a rounded corner feature 3412 with multiple intersecting surfaces can be provided in the edge area of ​​the stamping process clearance hole 345. The boss feature is that the edge of the stamping process avoidance hole 345 is partially arched towards the outside or inside of the plate to form a raised platform structure, which is used to enhance the deformation resistance around the hole area and improve the overall plate strength; the multi-faceted rounded corner feature 3412 is to set a transition rounded corner between the hole and the surrounding plate surface, especially to treat the intersection of multiple bending directions or rib lines as a rounded transition, so as to avoid stress concentration at sharp corners and improve the crack resistance of the plate during the stamping process.

[0071] The above-mentioned types of clearance holes not only meet the functional requirements of the product structure in the actual assembly and manufacturing process, but also reduce the overall weight of the reinforcing component 34 through local opening design. Under the premise of ensuring structural rigidity, they further meet the lightweight design requirements of new energy vehicles and other models. The opening structure can also assist in the heat dissipation or drainage function of the structure under special conditions.

[0072] In some implementations, in the electric tail wing mounting structure, such as Figure 2 , Figure 4-5 and Figure 11 As shown, the mounting component 22 includes a decorative panel 223 and bowl-shaped components 224 located at both ends of the decorative panel 223. The opening direction of the bowl-shaped components 224 is away from the inner panel 31 of the hatchback door. The driving mechanism includes a drive motor 23, a transmission component 24, and a drive hinge 21. The drive motor 23 is fixed on the decorative panel 223. The drive hinge 21 is disposed inside the bowl-shaped component 224. The drive motor 23 drives the drive hinge 21 to move through the transmission component 24. The electric tail wing 1 is mounted on the drive hinge 21.

[0073] Mounting component 22 includes a decorative panel 223 integrally formed or assembled, and bowl-shaped components 224 respectively disposed at both ends of the decorative panel 223. The decorative panel 223 and the bowl-shaped components 224 are used to cover and cooperate with the surrounding area of ​​the mounting window 321 on the outer panel 32 of the hatchback door, serving the dual functions of aesthetic coverage and structural support. The bowl-shaped components 224 have an outward-facing structure, that is, their opening direction is opposite to the inner panel 31 of the hatchback door. This configuration is beneficial for covering and concealing most of the drive mechanism through the decorative panel 223, and while ensuring a compact appearance, the bowl-shaped components 224 provide the necessary space to cooperate with the external electric tail wing 1.

[0074] The drive motor 23 of the drive mechanism provides the power source for the opening and closing of the electric tail wing 1. The transmission component 24 transmits the rotational or linear motion of the drive motor 23 to the drive hinge 21, which directly drives the opening or closing action of the electric tail wing 1, realizing the raising or retracting function of the electric tail wing 1. The drive motor 23 is fixedly mounted on the decorative plate 223, and can be reliably connected to the decorative plate 223 by means of screwing, riveting, or positioning buckle. Its output shaft is connected to the transmission component 24, which can be in the form of a gear set, worm gear, linkage mechanism, etc., to effectively transmit power. For example, the transmission component 24 shown in the attached drawings of this application is a linkage mechanism.

[0075] This implementation achieves modular installation and space integration optimization of the drive mechanism through the integrated mounting component 222 of the decorative panel 223 and the bowl-shaped component 224. The decorative panel 223 provides a smooth transition to the outside, maintaining the integrity of the rear appearance, while internally carrying the power components.

[0076] Preferably, the drive hinge 21 has a movable end 211 and a fixed end 212. The mounting point 111 of the electric tail wing 1 is installed on the movable end 211 of the drive hinge 21, which allows for precise adjustment of the tail wing's motion attitude. Four mounting points 111 are symmetrically arranged on the left and right sides of the electric tail wing 1. The fixed end 212 of the drive hinge 21 is installed on the bottom of the cup-shaped member 224, and can be fixedly connected by bolts to support the electric tail wing 1 and withstand the aerodynamic loads during high-speed travel.

[0077] like Figure 4 As shown, the periphery of the decorative panel 223 is provided with partially symmetrical first bolt mounting holes 222. The outer panel 32 of the hatchback door around the mounting window 321 is provided with partially symmetrical second bolt mounting holes 322. The second bolt mounting holes 322 on the outer panel 32 of the hatchback door correspond to the first bolt mounting holes 222 on the decorative panel 223 to achieve the connection between the outer panel 32 of the hatchback door and the decorative panel 223.

[0078] In some embodiments, in the electric tail wing mounting structure, two reinforcing members 34 are correspondingly provided and located on both sides of the extension direction of the mounting window 321. This arrangement allows the two reinforcing members 34 to provide symmetrically distributed structural support points on both sides of the electric tail wing 1 mounting area, facilitating the distributed installation of the drive mechanism and significantly improving the overall torsional stiffness and impact stability of the entire electric tail wing mounting structure. Each reinforcing member 34 can adopt a configuration with a "triangular support structure" or a "spatial cone closed-loop structure" as described above, giving it excellent force path design and spatial positioning characteristics, thereby maintaining long-term reliability under dynamic loads during the deployment, closure, and operation of the electric tail wing 1.

[0079] To further achieve the connection between the reinforcing member 34 and the outer panel 32 of the hatchback door, such as Figure 6 As shown, a welding recess 349 is provided on the second folding plate of the reinforcing member 34. The welding recess 349 has weld points for connection with the corresponding structure of the hatchback outer panel 32. The reinforcing member 34 can also have necessary material reduction features depending on the specific installation and usage environment to avoid interference or facilitate processing, for example... Figure 6 The process avoidance and material reduction zone 3411 in the middle.
